Hi everyone!I'm trying to figure out how to implement NASA's chlor_a algorithm in R for MODIS-Aqua, SeaWiFS, and VIIRS-SNPP. The OCx part of it has been no problem, but I'm having trouble finding which wavebands and coefficients to use for the Hu color index algorithm. I've been look...

Hello,I'm trying to assess the performance of the ocean colour band ratio algorithms for a couple different regions and sensors, and finding new optimal coefficients for different polynomial degrees using R. I started out simply using the lm() function to find the least squares polynomial throug...
